To all whom t may concern:

Be it known that I, JOSEPH CAvARGNA, a subject of the King of Great Britain, residing at 379 Ladypool road, Birmingham, in the county of Warwick, England, a ent, have invented certain new and usci-ill Improvements in Cigarettes, of which the following is a specication. v

My invention relates to absorbent mouthpieces or plugs for cigarettes and comprises the hereinafter described improvement connected therewith.

It has'many times been previously proposed to provide a cigarette with a mouthpiece or plug of medicated cotton wool or other suitable absorbing and filtering material: the end of a cigarette has been plugged with loose cotton wool: a plug of cotton wool has peen inserted within a short-length cardboard tube and then this tube has been rolled up with the, tobacco in rolling a cigarette, and a plug has been formed -by rollmg up a fiat layer of absorbent material into cylindrical form to be inserted or rolled up with the cigarette.

According to my present invention I form a plug of medicated cotton wool or other.

suitable absorbent'material as formerly, 'but use during its formation, or' afterwardL a suitable mucilage to cause its particles to sufciently adhere to ultimately provide a plug which can be conveniently, and without any fear of losing its shape and size, handled for insertion into, or rolling up with the tobacco of, a cigarette. It is suiiicient to use the mucilage upon the longitudinal exterior only of the plug to form a thin external coating or layer, as this adequately binds the particles of the plug, gives it a smooth exterior, and makes it to a sufficient extent Aresistant against moisture and saliva. To f produce my plug I first roll a layer of cotton wool or other material u on a thin spit or wire, and then coat thisrolled up layer with a suitable mucilage by rolling the said layer upon a surface to which the mucilage is applied, thereby binding the particles of the cotton wool properly together and providing a thinexterior coating of mucilage upon the longitudinal surface of the rolled-up layer which in Ipreferably cylindrical and parallel. For

, commercial manufacture I preferably produce a long length of such coated rolled up absorbent, and then cut ofi1 from this plugs of the required length.

By the accompanying drawings and the Fig. 2.

description hereinafter my invention will be clearly understood.

Figure l shows the manner of treating the absorbent material previous'to the application of the mucilage. Fig. 2 shows the absorbent material after having been treated with the mucilage ready to be cut into a number of plugs. Fig. 3 represents one of these plugs, and, Fig. 4 shows its application to a cigarette. Fig. 5 is a sectional view taken along line -:z: of Fig. 4.

Upon a spit or wire length a I roll a layer of medicated cotton woo or other suitable material forthe pu'rpose, in the manner represented at cin Fig. 1, paying the requisite attention to the diameter of the roll in view of the size of the cigarette'for which it is to be used. While on the wire I roll the rolledup wool upon a surface coated with a suitable mucilage, which when dry binds the wool together and gives a coated` cotton wool length d' substantially in accordance with From this length, Fig. 2, I cut a number of plugs as in Fig. 3, the interior cotton wool e being externally coated with a cylindrical layer f of the mucilage. is flexible, perfectly easy to handle, and sufciently porous to admit the free passage therethrough of the products from smoking, at the same time iiltering the smoke and absorbing the nicotine. I now roll the plug Fig. 3 1n with the tobacco of the cigarette as represented in Figs. 4 and5 so that it becomes a part ofthe said cigarette at the end.

The use ofthe mucilage as described in the production-of the lug is the invention; it will be seen from Fig. l that the rolled layer is externally iufy and irre ular and quite unsuitable for handling an insertion 1n a cigarette, but that when treated with the mucilage as in Fig. 2 the particles of the layer are adequately bound and made to adhere and a length is produced which by the external coating of mucilage becomes smooth and regular upon its periphery without interfering with the flexibility of it, and it will be quite obvious that the above features are very important as its external diameter requires to be carefully considered in the vmanufacture of such a plug, because the plug has got to nicely fit' the cigarette paper so that it may be either rolled in 'or pushed in witlia good smoke-tightV j oint be- .tween the periphery of the plu and the paper of the cigarette. The muci age also ro- Sucli a plug ICO ros Y IIO vides between the interior of the plug an the A proof layer.

muc-ilage which is most advantageous in view of aroma and hygienic smoking viz um arabic, tragacanth, precipitate of chal a little ether or spirits of Wine, and a little albumen, glycerin, and chlorate of potassium, a suitable composition being made by carbonate of lime, 8.78,-gurn arabic 9.25', tracanth 2.25, ether 0.25. spirits of Wine 0.15', albumen, 0.65, glycerin 0.55, and potassium clilorate 0.15.

Having thus described my invention what Il claim and desire to secure by LettersA material With an external iiexible binding of mucilage.

In testimony WhereofI I have hereunto set my hand in the presence of two subscribing 1 Witnesses.
